The underlying cause of degmacytes is a result of the splenic macrophages removing Heinz bodies from the membrane of red blood cells, which results in a "bitten" appearance of the cell.

Degmacytes usually appear smaller, denser, and more contracted than a normal red blood cell due to the bites. The appearance of the "bites" in red blood cells may vary in number, smoothness, and size. These cells can also exhibit other peripheral effects.
